Default [Q] Device won't boot into Fastboot mode

Been trying all evening to get this device to KitKat since I think it's very clear Sony won't release such a thing. Clearly I've had no luck. What I get when I hold the volume up whilest plugging in is a red light followed by a green light. Does anybody know why or how to fix this, please let me know thanks.
